King Corn: A Food Documentary to Watch

"Everything on your plate is corn." That line, uttered by an interviewee in King Corn, is essentially the premise behind this new food-focused documentary. Much the way that Super Size Me uses a clever gimmick to take on the fast-food industry, King Corn follows two friends, Ian Cheney and Kurt Ellis, who move to Iowa to find out how this unassuming crop has made its way into so many grocery-store staples in the form of corn syrup, malodextrin, and other not-so-healthy ingredients.

With humor and a vagabond attitude, Cheney and Ellis establish a one-acre corn farm so that they can follow the life cycle of their crop. Along the way, they visit the Midwest's sprawling corn complexes and interview experts about how the highly subsidized crop has become an easy target in the fight against obesity. The movie opened this weekend in New York, and over the next few weeks will be showing in other cities, including LA, San Francisco, Austin, and Chicago.
